DISINFECTING DEVICE FOR TELEPHONE MOUTHPIECES.

Application filed April 15, 1926. SerialNo. 102,105.

This invention relates to disinfecting devices for telephone mouth pieces.

It is well known that owing to the unrestricted use of the telephones, especially the public telephones, Contagious matter is likely'to be deposited in the mouth piece by a person using the telephone. Many devices have been produced to remedy this unsanitary condition but none, as far as I am aware, fully met the requirements of sanitar and practical use.

he ob ects of m invention are to provide a comparative y simple and. inexpensive device which will be effective in preventing a deposit of contagium in the mouth piece; which maybe readily applied to or removed from the mouth piece, and which will not interfere with the transmitting quality of the telephone.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference bein had to the accompanying drawing in whic Figure 1 is a' fragmenta side elevation, partly in section, of a telep one having my device attached to the edges of the mouthpiece, the device being shown in section,

Figure 2 an enlarged plan view, partly broken away, of the device shown in Figure 1, showing a protective piece of sheet material as it is removed from the device, and Figure 3 a section'taken substantially on line 33 of Figure 2 showing the protective sheet material in section and attached to the device.

Referring to the drawings, 1 indicates a telephone transmitter. 2 the mouth piece,

and 3 my improved disinfecting device attached to the ed es of the mouth piece. The device is made from sheet material 4, preferably fabric, .cut in the form of a disk which is treated with a suitable disinfect-ant. The fabric is of such texture that it will retain a suflicient quantity of disinfectant and will not interfere with the transmitting qualities of the telephone. This fabric is stretched and retained in the stretched condition by reinforcing rin 5 secured to the edges of the fabric pre erably by gluing them thereto. The reinforcing rings are made from comparatively stiff material, such as paper or cardboard. An adhesive ring 6 is secured to one of the reinforcing rings preferably by gluing the non-adhesive side or ring 6 to the reinforcing ring.

When packing the devices in a box for shipment, a protective sheet 7 is stuck to the adhesive side 8 of ring 6. The devices may then be stacked in the box without danger of one sticking to the other.

To apply the device to a telephone mouth piece, the protective sheet 7 is removed from the adhesive ring by pulling it off with the fingers, and the adhesive ring is stuck to the edge 90f the mouth piece by pressing the device against the mouth piece, as shown in Figure 1. With the device attached in this manner-the telephone may be used in the usual way, and any contagious matter which may be deposited on the antiseptically treated fabric by the erson using the telephone, will be destroy-e5.

comparatively simple device is thus produced which maybe quickly applied to or removed from the mouth piece and which is effective in destroying bacteria deposited thereon b the person using the telephone. The rein orcing rings keep the fabric in proper position and the device in proper shape during handling in transportation and use.

While [I'have described my invention as taking a particular .form, it will be understood that the various parts may be changed Without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A device of the character described for telephone mouth pieces comprising an antiseptically treated fabric; stiff reinforcing rings secured to the edges of the fabric, and an adhesive ring secured to one of the reinforcing rings whereby the device may be attached to the edge of the mouth iece.

2. A device of the character escribed comprising an antiseptically treated fabric; stiff reinforcin ringsglued to the opposite sides of the fa ric near its edges, and one of the reinforcing rings carrying a ring of adhesive whereby the device maybe attached to the rim of the mouth iece.

In testimony whereof have signed my name to this specification.
